Cons:
-Lag time on more than about 10 objects placed on the photo
-Bad placement of developer's website link
-limited to 14 objects
-lacking objects from running sports (marathons, track, ice skating)

Sports Brush is a simple photo editing application that allows you to add multicolored, multi-transparent, sport-themed shapes on top of your photos.

There are a total of 14 shapes (a baseball, a basketball, a bat, a bocce ball, a bowling ball, a football, soccer ball, a helmet, a hockey stick, a ping pond paddle, a rugby ball, a tennis ball, a volleyball, and a solid circle) and several colors for each one.

Layout:
When you first open the application, you simply select a photo from you photos or take a picture with the iPhone camera. After selecting a photo, you will view the photo and in the bottom left-hand corner you can tap in the brush-icon as this will take you to the object-select screen.
Here you can select the object of the left side and the color on the right side. Below that are a set of sliders. The top one controls the diameter of the object and the second slider controls the transparency of the object(s) being placed on the photo. Below the sliders are to on/off buttons. The left one allows you to randomize the shape and the transparency of the object (overrides the sliders) and the right one, allows you to randomize the colors. I personally found that having the these two on as the results were quite neat. Once you have finished selecting you options, tap the sketch button at the top to return to your photo. You can then use your finger as the brush on the photo. You can always return to the objects and color by tapping the brush in the lower left corner. To save the picture you tap the save icon in the lower right-hand corner of the screen.

Issues:
The first initial objects came out very quickly, but after subsequent objects were placed on the photo there was a considerable amount of lag time. This isn't really a problem if you are placing the objects one by one, but if you are trying drag your finger across the image- the lag time is very frustrating.
The undo button is okay it undoes the objects one-by-one. If you are wanting to remove several or completely, it is going to take you some time to complete.
The screen where you select from the pictures or the camera, in the bottom right-corner is an info screen (nothing wrong with this). In the bottom left-hand corner, is an icon that take you out of the app and into Safari.app to take you to the developer's website. While I am not opposed to having a website link, I think it should be in the info tab, not on the main interface because it can catch people by surprise and ruin the user experience.

Overall:
I think this is a nifty little application, but I really would like to see more objects added to the list. At $0.99 , this not a bad application to get started with.
